Definitions

  • the present invention is concerned primarily with the design and operation of a low cost, miniature portable capacitive electric current generator able to generate useful amounts of electric current in response to incidental movements of a part of a device such as the flip of a cellphone.
  • the generator is envisaged as being especially useful in supporting the power supply to portable electronic devices, such as mobile phones, personal digital assistants, global positioning systems, MP3 players, personal and/or implanted medical devices and so on. It should be understood that the application of the generator is potentially to any small, miniature device requiring an electric charge to operate and is not to be limited to the examples given above.
  • the generator of the invention aims to serve devices with average power consumption of the order of 0.1W to 4W and peak consumption of 10W may be served by the generator, however devices of larger or smaller power consumption may be served.
  • An alternative mechanism for electrical charge generation from a mechanical motion is the generation of an electric field in a capacitor which is then varied by means of a mechanical movement of part of the generator in order to induce charge to move through a conductor.
  • An early example of such an electrostatic capacitive generator is described in the US 4,127,804 .
  • two variable capacitors are mounted on a common shaft. Each plate of each capacitor is a segment of a disk. One plate of each of the variable capacitors is mounted as a rotor on the shaft while the other plate is mounted as a stator.
  • each of the capacitors is such that as the shaft rotates the distance between the plates of each capacitor changes so that their respective capacitance varies in anti-phase, one rising to a maximum as the other falls to a minimum.
  • the respective capacitor plates are electrically connected by a conductor via a load. Initially a priming charge must be loaded onto one of the capacitors. Any mechanical force causing the driveshaft to rotate will cause the capacity of the charged capacitor to fall while the capacity of the uncharged capacitor rises, charge will therefore flow reciprocally between the capacitors as an alternating current.
  • the flow of alternating current can be used to induce a charge onto an accumulator such as a chemical storage cell for later use.
  • volumetric efficiency is an expression relating the useful energy output by a generator to the energy input and the volume of the generator. Once discharged, the priming charge must be replaced or the generator will not work at all.
  • US 4,897,592 discloses a device in principle similar to that of US 4,127,804 which also has unsatisfactory volumetric and overall efficiency, but addresses the problem of the priming charge discharging by the somewhat unsatisfactory suggestion that the electrostatic priming charge be applied to the capacitor plates of the generator by an external energy source such as a battery.
  • electret based device In an effort to circumvent the priming charge problem more recent development has focused on electret based device.
  • electret based device is described in US 2004/0207369 .
  • Such devices are different from capacitance-based devices in that the electret is a component formed of a material which permanently stores an electrostatic charge applied to it during the production process. This charge cannot leave the electret but is used to induce a movement of charge by moving the electret relative to two nearby electrodes.
  • electret-based generators overcome one of the principal disadvantage of capacitance-based generators. Unfortunately electrets are prohibitively expensive and so uneconomic for most applications.
  • the charge density of electret generators is significantly less good than that for capacitor based generators so that electret based generators cannot achieve similar high overall or volumetric efficiencies.
  • a capacitive electric current generator as defined in Claim 1.
  • the permittivity of the dielectric may be varied by having at least two overlying layers of dielectric, each formed of regions of dielectric of different permittivity arranged across their confronting surfaces.
  • One dielectric is mounted to be displaced relative to the other so that regions of high permittivity coincide on each plate in one position and regions of high and low permittivity on opposing plates coincide in another position.
  • the overall value of permittivity of the dielectric can change from a high value to a low value, so changing the capacitance of the capacitor.
  • Relative movement of the dielectric layer can readily be achieved by a transmission which may displace the dielectric linearly or rotationally. Displacement is preferably parallel to or tangential to the layer. Preferably the displacement is achieved without changing the volume of the capacitor.
  • the capacitance of the capacitors may be varied synchronously and/or in antiphase to effect the change in capacitance.
  • the mechanical transmission may be coupled to structures of the portable device such as a push button, sliding cover or flip open cover, a hinge or a squeezable handle, so that the muscular effort of, for example, opening the device for use, drives the generator.
  • the generator may be implemented as a stand alone device for delivering charge to other devices.
  • the generator may be implemented into the a shoe to recover power from the action of a wearer walking.
  • Figure 1 is the electric circuit diagram for a generator of the present invention, this consists of a variable first capacitor 1 and a variable second capacitor 2. As can best be seen in figure 2A the generator consists of three discs A, B and C coaxially mounted around a driveshaft 18.
  • Disc B is mounted between discs A and B coupled to the driveshaft 18 for rotation, while the upper and lower discs A and C are irrotatably mounted in relation to the driveshaft and the disc B.
  • each disc is divided into an inner annulus marked as G, and an outer annulus marked P. Rings R electrically isolate the annuli. As will be described below the inner region provides the generating circuit G, while the outer annular regions of the discs provide a self priming circuit P.
  • Figure 3A is a plan view of the assembled generator from above in figure 2A .
  • the lower face of discs A and the upper face of disc B are similar.
  • Figure 3B shows the upper face of disc C in plan.
  • Figure 3C illustrate the lower face of the disc B which is obscured in figure 2A .
  • variable capacitors 1, 2 each comprise two opposing annular plates.
  • the first capacitor 1 comprises opposing plates 3 and 5 while the second capacitor 2 comprises opposing plates 4 and 6.
  • the plate 3 is provided on the disc A in figure 2 the plates 4 and 5 on the disc B and the plate 6 on the disc C.
  • Each of the opposing plates 3, 4, 5, 6 consists of a layer of electrical conductor 9, 10, 11, 12 and a dielectric layer 13, 14, 13a, 14a is bonded one each to each conductive layer 9, 10, 11, 12 to prevent electrical charge from crossing the gap separating the plates while remaining to some degree pervious to the electric field.
  • Each dielectric layer 13, 13a, 14, 14a is divided into regions 15 (shown in crosshatch) having a low dielectric permittivity and regions 16 (shown clear) having high dielectric permittivity.
  • regions 15 shown in crosshatch
  • regions 16 shown clear
  • the regions of high and low permittivity extend radially, as segments of similar size, from an inner annulus near the centre of the disk to an annulus toward the rim of the disc. It will be noted that the regions of high and low permittivity on plate 4 are rotated relative to the other plates 3, 5 and 6 which all resemble figure 3B .
  • variable capacitor uses confronting layers of dielectric material, the maximum dielectric permittivity of the layer can be very high by comparison with air. Actual values will depend on the dielectric selected.
  • Each of the plates 3, 4, 5, 6 is mounted coaxially around a transmission provided by the driveshaft 18.
  • Rotor plates, one each for each capacitor are provided by mounting one of the plates 5, 4 of each capacitor 1, 2 on the driveshaft 18 to be relatively rotatable with respect to each of the stator plates 3, 6. It can be readily understood from this arrangement that as the rotor plates 4,5 turn the regions of high dielectric permittivity 15 of the opposing plates of each capacitor 1, 2 alternately align themselves in opposition, as shown in the capacitor 1 of figure 4A and then adjacent as shown in the capacitor 2.
  • the alignment of the rotor plates of the capacitors 1, 2 is as shown in figure 4A such that when one rotor plate has its dielectric regions fully aligned in opposition, the other has its dielectric regions fully adjacent.
  • the difference in permittivity of the regions 15, 16 can be achieved either by the deposition of materials of different permittivity onto the conductive layer, or by different treatment of a single dielectric layer over the regions to induce a desired change in the dielectric properties.
  • the plates of the capacitor may thus be fabricated by known processes such as printing or plasma deposition onto a suitable substrate.
  • a spacer or bearing member 17a, 17b may be provided between the opposing faces of the dielectric layers.
  • Each the conductive layer 10, 11 of each stator plate 3,6 communicates via a conductor 7, 7a with the conductive layer 9, 12 of the rotor plate 5, 4 of the other of the capacitors.
  • the conductor layer 11 of the plate 3 communicates with the conductive layer 12 of the rotor plate 4 via conductor 7 while the conductive layer 9 communicates with the conductive layer 10 via the conductor 6A.
  • the energy extraction device is a load, for example a transformer.
  • the energy extraction device 8 electrical energy is drawn off, without discharging the priming charge Q, and may then be used as desired.
  • the energy may charge a chemical cell or some other form of accumulator.
  • each capacitor is varied without altering the distance between the conductive plates 9, 11 of the first capacitor or 10 and 12 of the second capacitor 2.
  • the use of a dielectric layer between the conductive plates of each capacitor which has a variable permittivity allows the capacitors to store a large charge at high-voltage allowing a high energy density and correspondingly relatively higher power generation performance than hitherto possible with similar devices.
  • the volumetric efficiency can be enhanced by polishing the confronting surfaces of the dielectric layers to a high degree and minimising the gap, which may be an air gap between them.
  • Capacitance is C 0 / 1 + ⁇ ⁇ / d
  • the design of the capacitors allows the generator to be manufactured at low cost while exhibiting high performance and a high degree of reliability.
  • FIG. 1 A problem arising with any form of capacitor-based generator is the gradual loss of the priming charge.
  • the generator of the present invention is provided with a self priming circuit 101 which as a consequence of movement conveyed by the transmission 18 will generate or restore the priming charge on the generator capacitors, as illustrated in figure 1 .
  • This circuit 101 consists of two variable priming capacitors 102, 103 of design similar to that of the generator capacitors 1 and 2.
  • a structural drawing of the self priming capacitors is provided by figures 2A , 2B and 2C .
  • Figure 7A illustrates the phase alignment of the capacitor plates.
  • Figure 7B is a circuit diagram illustrating the charge condition of each component in a first phase illustrated in figures 7A and 7B .
  • the priming capacitors 102, 103 each consist of a pair of annular plates 104, 105, 106, 107.
  • the plate 107 is provided on the outer annulus of stator disc C.
  • Plates 106 and 105 are provided in back to back relation on the rotor disc B and plate 104 on the stator disc A.
  • Each plate 104, 105, 106, 107 is formed from a respective conductive layer 104a, 105a, 106a, 107a on which is deposited a dielectric layers 103b, 104b, 105b, 106b respectively.
  • the conductive layers of the priming capacitors are separated from the conductive layers of the generator capacitors, on the same disc, by the electrically isolating rings R.
  • the dielectric layers of the priming capacitors 102, 103 are separated into alternating radially extending regions of high dielectric permittivity 115 (the crosshatched segments in the drawings) and low dielectric permittivity 116 (the clear segments). arranged to vary in phase as the plates are displaced by the transmission shaft 18 as can be discerned from figures 3B and 3C as well as figures 8 - 11 .
  • a switch system 108 is driven synchronously with the change in capacitance induced by relative displacement of the plates 104-107.
  • the switch system consists of three switches K1, K2 and K3 respectively.
  • the switch K1 is arranged to electrically isolate or communicate between the plate 104 of the first priming capacitor 102 and the plate 106 of the second priming capacitor 103.
  • the switch K2 is arranged to electrically communicate or isolate the plate 106 with the plate 105 of the first priming capacitor 102.
  • the switch K3 is arranged to electrically communicate or isolate the plate 105 with the plate 107 of the second priming capacitor 103.
  • the self priming circuit may rely on the presence of at least a small residual charge on the generator capacitors 1, 2.
  • a residual charge is one much less than the priming charge, for example 10% or 1% or 0.1%. Its actual value will depend on the conditions of operation as well as the construction of the priming capacitors. This can be ensured by careful selection of the material from which the capacitors are constructed.
  • Preferred materials include Barium Titanate, Barium Strontium Niobate because of their high dielectric permittivity. Such materials retain at least a small electric charge indefinitely.
  • Friction may be caused by the action of the rotating dielectric pressing against a spacer 102a, 103a interposed between the opposing dielectric layers. This may be sufficient to initiate the self priming process described below.
  • the residual charge (Q) is illustrated as being present on the generator capacitor 2 arranged to communicate with the plates 104 and 107 as shown in figure 1 when read with figure 8A .
  • the switches of K1, K2 and K3 are all open and there is no charge on any of the priming capacitor plates.
  • Figures 8A and 8B show the second phase of the self priming process where rotation of the rotor B causes the switches to set K1 and K3 open and, K2 closed the residual charge source initially communicates with the priming capacitor plates 104 and 107 raising the charge on those plates to +q and -q respectively. In consequence an equal and opposite charge is induced on the opposing plates 105, 106. It will be noted that at this stage the dielectric regions are aligned to maximum permittivity in both capacitors 102 and 103. The charge on the generator capacitor plates changes to +(Q-q) and -(Q-q).
  • the design of the self priming circuit can advantageously be implemented in a rotary generator by constructing the priming capacitor plates 104-107 on annuli of the same structural discs forming the generator capacitors.
  • the switches K1, K2, K3 may conveniently be provided on the outer surfaces of the stator discs A and C to be actuated by the rotation of the shaft relative to the stator disc.
  • the switches may be fabricated into the portions of the rotor and stator discs A, B, C not serving as capacitors so that the relative rotation of the rotor disc and stator discs actuates the priming circuit switches.
  • the discs A, B, C and shaft 18 may form part of the hinge structure coupling the parts 21A, 21B of a flip phone 21.
  • the generator disks A and C may be mounted to the part 21A while the disc B is mounted to the part 21B, thus when the phone is flipped open the disc B rotates relative to the discs A and C.
  • Gearing (not shown for the sake of clarity) may be provided to one of the stator discs A and C or the rotor disc B so that the action of opening the flip phone causes several relative rotations of the discs.
  • the generators may be banked as shown in figure 11 so that a plurality of generators provide the hinge structure.
